------------------------------------

             Summary: Object reuse issue in combineValues(Aggregator)
                 Key: CRUNCH-501
                 URL: https://issues.apache.org/jira/browse/CRUNCH-501
             Project: Crunch
          Issue Type: Bug
            Reporter: Brandon Davis


I'm trying to use combineValues on a PGroupedTable. I am using Aggregators.FIRST_N. If I have
20 keys in my PGroupedTable, then I only get 20 distinct values because the AggregatorCombineFn
and FirstNAggregator don't detach the values from the incoming iterator.
